Field studies were carried out during 2005–2007 growing seasons on susceptibility of the following nine varieties of field pea: Eureka, Hubal, Kos, Marych, Pomorska, Milwa, Sokolik, Winerek, Zagłoba to infestation caused by larvae of pea moth. The experiment included four replications and was set up in a randomised block design. The following cultivars as: Milwa, Kos and Pomorska
demonstrated the highest percentage of damaged pods by pea moth larvae, ranging from 3.7 to 69.0%. The lowest per cent of damaged pods was shown by cv. Zagłoba and Sokolik (21.0 and 29.0%, respectively) in 2005, Winerek (3.7%) in 2006 and Sokolik (13.5%) in the 2007. The average yield of tested cultivars ranged from 16.0 dt/ha to 49.8 dt/ha, average 36.2 dt/ha.
